US fashion retailer American Eagle Outfitters is planning to add another retail format to its portfolio, which is being referred to as Concept Four.

The company's chief executive Jim O'Donnell told investors in a conference call this week that Concept Four would be leveraged to the maximum against the American Eagle brand.

He added that specifics of the store concept and additional colour would be provided early next year.

"This is going to be unique, we feel it is going to be special and we are all very very excited about it," O'Donnell said.

The retailer, which posted a 2% dip in third-quarter profit to US$99.4m this week, operates under the American Eagle Outfitters and Martin + Osa brands.

American Eagle sells casualwear to 15 to 25 year-olds, through 852 stores in 50 states. Martin + Osa, meanwhile, is a new sportswear concept targeting 25 to 40 year-old women and men through ten stores.

O'Donnell said it would take until spring or summer 2008 before the first indication of the financial success of the Martin + Osa concept would be determined.
